The aim of this study was to evaluate the silvicultural performance of the Jacaranda copaia in homogeneous plantation, under different spacing between plants at different ages, in the West of the State of Pará. They were installed in the Experimental Field of Embrapa Amazônia Oriental in the municipality of Belterra, Pará, four treatments, referring to the different spacings between plants: 3m x 2m; 3m x 3m; 3m x 4m and 4m x 4m. The variables used to evaluate the silvicultural performance were: survival, total height, diameter at breast height, basal area, volume per tree and volume per unit area. The Jacaranda copaia stand presented high survival and the population density did not influence the performance in this variable and in total height, however for the variable diameter there was a significant increase as the space between plants was enlarged. The higher density of individuals promoted the higher production in basal area, wood volume per hectare and volumetric increase. The silvicultural performance of the species at 3m x 3m and 3m x 4m spacings showed similarity in most variables and ages studied, with good performance in basal area and Average Annual Increase.
